Theory of Operation, explaining how the KSM module works:
Once installed and wired properly, the LED on the End-Faceplate of the KSM will
be illuminated green whenever the KSM contactor relay is closed. When the LED
is illuminated, the contactor is closed; the KAPower Module is running parallel
with the vehicle, vessel or equipment batteries and electrical system.
When the DPST switch is depressed you are closing the contactor inside the KSM
enclosure, using power from the KAPower module, regardless of the state of
charge of the vehicle or equipment’s batteries. When depressing the DPST switch
you are also engaging the cranking motor circuit, just as you would if you turned
the key switch to the crank/start position, or pressed the vehicle’s or vessel’s start
button if so equipped. The DPST switch is wired in parallel with the existing
starting system. This is done by wiring and using the recommended electrical
circuit, displayed on the schematic (page 13). By doing so, you have paralleled
with the OEM (Original Equipment Manufacture) electrical circuit allowing both
the KSM and the OEM cranking motor circuit to be engaged, simultaneously.
Once the engine starts, the Programmable Logic Controller (PLC) inside the KSM
monitors the condition of the KAPower Module and will close or open the
Contactor Relay inside the KSM, based on the preprogrammed parameters inside
the PLC. When the engine is stopped, the equipment is turned off, the contactor
opens and the KAPower module remains isolated, waiting for the next engine-
starting event, when the DPST switch is pressed.
The PLC preprogrammed functions:
The PLC has been preprogrammed to monitor and control the state-of-charge of
the KAPower capacitor module based on temperature, voltage & time. Once a
voltage signal is received at pin four (4) of the Wiring Interface Connector the
PLC “wakes-up” and will determine when and how long to keep the contactor
closed. Remember, anytime the LED Status Indicator is illuminated the contactor
is closed. In a typical engine-starting event you will see the LED illuminate during
engine cranking and then go out for several seconds after the engine has started.
The LED will then illuminate again and could remain illuminated for several
seconds based on the condition of the KAPower module. The LED may even begin
to “cycle” depending on the vehicle or system voltage during the recharging
events.
The J1939 connector is used for KBI Factory programing only. Contact KBI for
